Detailed description of the invention
Describe the present invention with embodiment below in conjunction with the accompanying drawings:
Embodiment: as shown in Figure 1 and Figure 2, the present invention is the cleaning of high vortex blade inner chamber residual fluorescence liquid
Method, to guarantee that residual fluorescence liquid can effectively be removed.Owing to high-pressure turbine blade is to use I class D method (parent
Emulsifying fluorescence after aqueous) method carries out Liquid penetrant testing, the more difficult removal of fluorescent liquid, use when using prerinse
Neutral cleaners cleaning performance limited.Therefore first use emulsifying agent to coordinate chuck that blade inner chamber is rushed
Washing, emulsifier concentration answers conformance with standard requirement, then connects clear water and rinsed well by the emulsifying agent of inner chamber,
Finally connect compressed air, blow down the moisture of inner chamber residual.Specifically include following steps:
(1) first blade outer surface is carried out normal developing, when carrying out the cleaning of blade inner chamber, by chuck
It is clamped on blade tenon, makes the biting teeth in chuck closely be engaged with the first row tenon tooth roller seating space of blade,
Check that chuck is ready for inner chamber and rinses after being engaged closed seamless gap with blade tenon；
(2) first with emulsifying agent, blade inner chamber is rinsed, to dissolve the fluorescent liquid of residual, particularly as follows:
Being connected with transfusion catheter by chuck conduit, be passed through emulsifying agent, the concentration of emulsifying agent should meet fluorescent penetrant
The requirement of examination criteria, the pressure of flushing should ensure that and emulsifying agent can be made from blade tip window and all of air film
Flow out at hole, make inner chamber without emulsifying dead angle, ask during flushing as the 30-60 second；
(3) by adapter, chuck conduit is connected with water pipe, rinses blade inner chamber with clear water,
To remove fluorescent liquid and the emulsifying agent of residual, flushing pressure is 0.17-0.27MPa, and washing time is 30-60
Second；
(4) by adapter, chuck conduit is connected with compressed-air line, by compression sky
The residual moisture of air-blowing disleaf sheet inner chamber, air pressure is 0.17-0.27MPa, and the blowing time is the 15-30 second.
After above step terminates, fluorescent liquid that blade inner chamber remains and moisture can be made to obtain good removal,
Blade inner chamber is near drying regime, then carries out follow-up part baking operation blade inner chamber can be made to obtain
It is further dried.So far blade inner chamber has obtained good cleaning, can realize consistent with blade outer surface
Cleannes and drying regime.
As shown in Figure 1 and Figure 2, the chuck that the present invention uses when clearing up blade inner chamber, including rustless steel
Plate make chuck shell 6, be coated in the rubber liner 2 inside chuck shell 6, rubber pouch 3 and
Conduit 7, described rubber liner 2 is the biting teeth coordinated with blade tenon 5 with blade tenon 5 joint place,
Rubber liner 2 connects one and has rubber pouch 3 elastic, corrosion resistant, and conduit 7 one end is passed through rubber bag tank
In bag 3, the other end installs adapter, by connecting transfer line and compressed-air line, and input
Liquids and gases；When chuck closes, rubber liner 2, rubber pouch 3, blade tenon 5 form one
Individual airtight space.Wherein chuck size should be more slightly larger than blade tenon 5.In use, chuck is pressed from both sides
Hold on blade tenon 5, be closely engaged with tenon tooth, it is ensured that not leakage liquid or gas, chuck tail end
Connect conduit 7, owing to rubber liner 2, the rubber pouch 3 of collet interior form one with blade tenon
Airtight space so that liquid and compressed air are fully injected into blade inner chamber, it is ensured that water, throughput without
Decay, it is ensured that blade inner chamber is effectively cleared up.
The outside of described chuck shell 6 is additionally provided with two steel wire rings 4 of clamp gripper.Utilize steel wire ring
The elastic force of 4 is as the source of grips power.
The rubber liner 2 of coating inside described chuck shell 6, thickness is 2-3mm.Can play sealing and
The effect of protection blade tenon 5.Biting teeth thereon closely can be engaged with row's tenon tooth of blade, prevents
Leakage liquid or gas.
